Got an iphone 6S plus and I'm finding I hardly ever use 3D Touch. Talking to 2 friends with the same phone and like me they never use it. On messages it's a farce. God knows which contact will appear when you use the app. Mail. Don't see where it saves time. Contacts. Useless. Twitter. No speed saving. WhatsApp. What's the point? I could go on and on but for me I really don't get this feature at all.
